At Cloudflare, we are on a mission to help build a better Internet. Today the company runs one of the world's largest networks that powers millions of websites and other Internet properties for customers ranging from individual bloggers to SMBs to Fortune 500 companies. Cloudflare protects and accelerates any Internet application online without adding hardware, installing software, or changing a line of code. Internet properties powered by Cloudflare all have web traffic routed through its intelligent global network, which gets smarter with every request. As a result, they see significant improvement in performance and a decrease in spam and other attacks. Cloudflare was named to Entrepreneur Magazine's Top Company Cultures list and ranked among the World's Most Innovative Companies by Fast Company. At Cloudflare, we're not looking for people who wait for a polished roadmap; we're looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you're the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you'll fit right in. Available Location: Lisbon, Portugal or London, UK Role Summary As a Senior Jira Systems Administrator, you will serve as the primary architect and guardian of our Atlassian Data Center environment, ensuring peak performance, security, and scalability. You will collaborate closely with cross-functional internal teams to translate complex business needs into streamlined workflows while leveraging Groovy and ScriptRunner to automate advanced logic. We are looking for a meticulous, "uptime-focused" technical expert who balances deep infrastructure knowledge with a commitment to maintaining a clean, well-governed instance. Role Responsibilities System Maintenance & Security: Lead the end-to-end patching process for Jira Data Center/Server instances. Monitor Atlassian Security Advisories and perform version upgrades to ensure the environment is secure and performant. Instance Governance: Serve as the primary gatekeeper for the Jira configuration. Manage global settings, including workflows, permission schemes, screen schemes, and custom field consolidation. Automation & Customization: Develop and maintain complex scripts using ScriptRunner (Groovy) to automate business logic, extend Jira's native capabilities, and integrate with external APIs. Performance Monitoring: Conduct regular health checks, JVM tuning, and re-indexing. Troubleshoot system-level issues (logs, database connectivity, or plugin conflicts) to minimize downtime. User Support & Training: Provide "Tier 3" support for internal teams, helping them translate business requirements into efficient Jira projects without creating "configuration bloat." Must-Have Skills Atlassian Expertise: 3-5+ years of experience as a Jira Systems Administrator, with specific experience both in On-Prem (Data Center or Server) environments AND cloud migration experience. Scripting Proficiency: Advanced knowledge of Groovy and the ScriptRunner plugin. You should be comfortable writing scripts that interact with the Jira API. Infrastructure Knowledge: Strong understanding of the underlying tech stack: Linux/Windows servers, SQL databases (PostgreSQL/SQL Server), and SSL/Certificate management. Technical Troubleshooting: Ability to analyze log files (atlassian-jira.log) and thread dumps to identify the root cause of system instability. Change Management: Experience operating in a production environment where "uptime is king," following strict change-control processes for all patches and updates. Nice-to-Have Skills Atlassian Certified Professional (ACP): Current certifications such as ACP-100 (Jira Admin for Data Center) or ACP-120 (Jira Admin for Cloud). Identity Management: Experience with Atlassian Guard (Access) and configuring SSO/SAML (e.g., Okta, Azure AD) for user provisioning.
